and has for its object to provide a separator which shall be independent of the carbureter and interposed between the carbureter and theintake of the enginewhereby the charge after leaving the carbureter will be broken up and screened with a view of effecting a better mixture of air andgas and at the same time extracting condensed particles of .liquid such as raw gas or. water so that a more perfect gas charge will enter the engine itself. H v r p p The invention is illustr ted .in the accompanying drawings, where1n,-

- Referring to the drawings the numeral 10. a designates the base of an internal combustion engine on which the blocks 11 containing the cylinders are mounted, and 12 desgnates the, head to which the intake inanifold :13, is connected so as to deliver, the charge through the head to the cylinders n.

the usual manner. I

p The carbureter .14, of anydesired make or style shownattached to the basefwith a I conduit 15, leading therefrom toward the intake manifold so as to convey the usual charge of gas and air.

Between the carburetei' 1-1 and thephead' 12 I locate my improved separator devic'e,

the preferred way of attaching it being to in terrupt the intake manifold-pipe or conduit and place the separator at the interrupted point sothat the charge ofgas and air will pass from the carbureter through the separator and then to the engine.

In the present instance I prefer to locate thethrottle-valve stem 16 on} the outer end ,of which there is the usual lever 17, so that an actuating rod 18, when moved by' the a driver willopen or close thethrottle-valve as desired. i I

Frointhe foregoing explanation it is to be clearly understood that the improved separator is in nosense acarbureter; is no part of the carbureter but receives the charge on its way from the carbureter to the engine.

In'the present form of separator the same has a. lower flanged plate 19 with bolt-holes 20 at opposite ends thereof and with a cen- .tral aperture 21, which registers with the passage of the conduit 15. The upper side of this plate is provided with an annular drain-groove or channel 22, around the aperture and a passage23, extends/through the f plate and is connected by a drain-tube 2 1 011 the exterior, for, purposes presently to bee);- plained. I i i, At opposite sides'of the drain-groove or tending posts 25 which serve a useful'purpose as will presently appear. v

A tube 26 seats on topof the plate 19 around the drain-groove 22 and this tube extends vertically between the twoposts.

At the center of the tube 26 I locate" a cylindrical frame 27 whose lower end seats on the upper side .of the plate 19 around the channel 22 the plate 19 has vertically-excentral aperture 21 and said frame extends vertically in thetube 26'. I

The cylindrical frame 27 has circumferential openings 28 between its upper and lower ends, and closely about the frame, and

covering said openings, there is a tube 29 of fine wire mesh.

'In the present form I second tube soot fine wire which latter has position between the wire tube 29- and'the outer tube 26. r y r I further provide a r It will thus be seen that a plurality of screens are provided between the outer tube 26 and the cylindrical frame 27.

All of these tubes 26, 29 and 30 and the cylindrical frame 27 are held down in place by a top plate 31 of the separator which plate is locked in place by means of screws 32 that pass down into the posts 25.

A washer 83 is preferablyplaced on top of the screen 30 and also on the cylindrical frame 27 so as to seal the interior chambers. The top plate 31 also hasfa central aperture 34 which alines on the under side with the interior of the cylindrical frame and on its upper side communicates witlrthe passage in the intakemanifold 13. I

Bolt-holes 35 are provided. at opposite sides of the to-p-plate31 so that the entire separator maybe attached to the manifold and the conduit by two bolts 36 as shown in Fig. 1, of the drawing.

The interior of the cylindrical frame 27 is provided with a spider 3'7 which is rigidly held therein between the top and bottom and on the under side of this spider there is carried a head having a series of blades 38.

Near the bottom of the cylindrical frame, I provide a'series of stationary blades 39 to which I rotatably mount a series of movable blades 40. These movable blades are connected to the inner end tl ofa crank lever which latter extends through and has bearing in the bottom plate 19 and the outer end 42 of this lever is connected by a rod 43 to the throttle-actuating lever 17, so that when the throttle-valve lever 17 is operated to open the throttle'valve, the rod 4-3 and lever. -i2:t1 will be moved to rotate the blades and increase the size of the openings up through the cylindrical frame. These blades 3.9 and 40 therefore serve as a damper and open when the quantity of gas is increased but close down as the quantity of gas from the carbureter is decreased.

At the top ofthe cylindrical. frame, I provide a series of curved blades 44., which serve as a baffle to prevent the gas from passing straight through and which also keeps the gas in a whirling motion during its passage therethrough.

The drain-tube 24. from the channel 22, is connected to a tube 45, which latter in this instance leads back to the carbureter so that any liquid flowing from the separator may be carried back to the carbureter. A check valve 46 is provided in this tube to prevent any interference with the intake suctions and to also prevent the liberated liquid after it passes the valve from being drawn back toward the separator.

In the operation of the device as the gas is drawn toward the intake manifold 13, it

' will pass up into the cylindrical frame, be-

ing given a whirling motion as it enters. it strikes the rotating blades 38, it'will be subjected to centrifugal forces and thrown laterally through the screens, during which operation the gas will be broken up. Any liquid suchas an excess quantity of liquid gas will be collected on the screens from which it. will flow downwardly into the groove 22 with the result that the gas will be more thoroughly mixed and the liquid removed. Such liquid as is removed will flow from groove or channel 22 through passage 23 to tubes 24 and 4:5 and thus be carried off.
